Photosynthesis: Plants ka food factory

Plants apna khana sunlight se kaise banate hain? Aaj samjhenge!

Photosynthesis matlab: light energy ko chemical energy mein convert karna, jisse plants ko food milta hai.

Photosynthesis ke liye teen cheezein zaroori hain: sunlight, water aur carbon dioxide.

Ye sab kuch plant ke leaves mein hota hai, jahan par chlorophyll naam ka green pigment hota hai.

• Chlorophyll = green colour

Pehle step: Light-dependent reactions. Sunlight chlorophyll ko energy deta hai.

Is process mein pani ke molecules break hote hain aur oxygen nikalta hai, jo hum breathe karte hain!

• Oxygen byproduct hai

Dusra step: Dark reactions ya Calvin cycle. Yahan carbon dioxide se glucose banता hai.

Calvin cycle mein ATP aur NADPH use hote hain, jo light reactions se aate hain. Poora equation likhen toh: six carbon dioxide plus six water, sunlight se, glucose aur oxygen banate hain.

• ATP aur NADPH = energy carriers

Ek example: ek mango tree ko dekho. Subah sunlight milti hai, leaves photosynthesis karte hain.

Jab glucose ban jata hai, plant use ko store karta hai starch ke form mein roots aur fruits mein.

Yeh stored energy hi plants ko grow karne mein madad karta hai aur hume food bhi deta hai.

Photosynthesis ke bina oxygen nahi hota, aur complex life Earth par possible nahi hota. Ab ek quick quiz: Photosynthesis mein oxygen kahan se aata hai? Toh yaad rakho: sunlight plus water plus carbon dioxide equals glucose plus oxygen—yeh hai plants ka magic!

• Oxygen = life ke liye zaroori
